Dynamically Generate Image On Image Map Or Image Button?
Sep 30, 2010
Here is this thing which to me looks possible, but when I searched over the net I couldnt find anything.
I want to create a page where I can upload an image using any upload function and then display it. Now after diplaying it I want to select the hotspots for an image map. The coordinates of image map values are stored in a database.
Basically I want that to create image maps and hotspots I dont use any offline software, this work is successfully completed and working perfectly, but i want generate one identification where i click the hot spots position in image or CSS file Generate for user identifications, So how can i solve this problem.
I hope You are clear in that what I am looking for.
Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.
I am trying to change the image url of an image button in my gridview. I cannot seem to be able to do this in the code behind. Is there a way I can do this through the image buttons controls?
I am new to .NEt, I am doing a classifieds website and tried to save the image in server,in a seperate folder and stored that address in MS access databse.when I wanted to display that image in a gridview,its not showing the image.
In the seperate column when Ia m trying to see the image location using bound field,its displaying C:websitesAzangouser_images j.jpg, but where as its not showing the image in the item template field.
I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel:
[Code]....
in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!
I have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.
I am trying to put a default image in an Image control in asp.net and it should show that particular image on the page when no other image is assigned or no image available in Database.
I know how to display an image in gridview from image path in database. Now, I want to display an image in an asp.net image control from image path in database. Can anyone point me to a tutorial? I haven't been able to find one that explains how to do it when I don't know what the image path will be. The images are in the root folder.
iam trying to create image button in the pageload with clickevent dynamically but iam getting error. i have searched many blogs but i cant overcome with the problem.
'System.Web.UI.ImageClickEventArgs' does not contain a constructor that takes '1' arguments. example shows how iam creating imagebutton in the pageload ImageButton ib = new ImageButton();
I'm not even sure if this is the correct approach for this -
I have a DB that stores information, as well as a location to where images are stored
ie ProductImage = ~/ProductImages/BulkRetail.JPG
I'm using a repeater to list all the products, which works fine for all the labels I use but not for the image location. I'm using something like this, but it doesn't work:
I have div In my page that in this div I put image control
<div id="DLogos"> <asp:Image ID="imglogo" runat="server" CssClass="ILogos" /> </div> according to below code <div id="Dart1_I1" visible='<%# !string.IsNullOrEmpty(Eval("image1").ToString())%>'>
If in database was image it show div and if there wasn't any image it didn't show div but above code is for div that I put in datalistnow I want do some thing like that for Div that I don't put it in datalist I should write code for that in behindecode page but I don't know How I can do it?behind code
SqlCommand _cmd = new SqlCommand("storeinfo1", _cn); _cmd.CommandType = CommandType.StoredProcedure; _cmd.Parameters.AddWithValue("@behcode", data); _cn.Open(); SqlDataReader _dr = _cmd.ExecuteReader(); while (_dr.Read())
